Rewrite Exponential Expressions

Answers

Answer 1

Answer:

A = 48

Step-by-step explanation:

In this equation, we can factor out the expression [tex](\frac{1}{7} )^x[/tex]. If we do so, the expression becomes:

[tex](\frac{1}{7})^x((\frac{1}{7})^{-2} - 1)[/tex]

We can simplify to get:

[tex](\frac{1}{7} )^x(49 - 1)[/tex]

and get:

[tex]48*(\frac{1}{7})^x[/tex]

Therefore, A = 48

Translations, rotations, and reflections are rigid transformations. What can you conclude about the measures of sides and angles on any triangle after undergoing a series of rigid transformations? Explain.

Answers

Answer:

After a translation, the measures of the sides and angles on any triangle would be the same since translation only involves changing the coordinates of the vertices of the triangle.

After a rotation, the measures of the sides and angles of a triangle would also be the same. Similar to translation, the proportion of the triangle is unchanged after a rotation.

After a reflection, the triangle's sides and angles would still be the same since reflection is a rigid transformation and the proportion of the sides and angles are not changed.

Step-by-step explanation:

Rigid transformations, i.e. translations, rotations, and reflections, preserve the side lengths and angles of any figure. Therefore, after undergoing a series of rigid transformations, the side lengths and angle measures of any triangle will be the same as the original triangle, generally speaking, in another position.

Answer:

They are all congruent or equal. The angles and side lengths are preserved through the rigid transformations.

What are traffic rules?

According to the Traffic Ordinance, disobeying a rule or following a piece of advice inside the Road Users' Code is not in and of itself an offense, but any such rejection may be looked into in any deliberations (as to if civil or criminal, including litigation for an offense underneath the Road Traffic Ordinance), and may also be relied upon for establishing or negating any liability.

However, it should be emphasized that several of the guidelines in the Car Drivers' Code exactly mirror the law, and anyone who violates these guidelines may be breaking the law.

It means that on rainy days, divers drive very carefully as compared to other days.

68640 / 15 = 4576.

we now see there are 4576 cars in the traffic jam.

Less, they are longer cars so the divosor would no longer be 15, it would be a higher number. 4576 cars would  not be able to fit in a 13 mile stretch if those cars were any longer.

Samuel bought an 8-ounce bag of lettuce and two 1-pound bags of carrots. Which is the total weight of the lettuce and carrots in ounces?
A. 10 ounces
B. 12 ounces
C. 40 ounces
D. 72 ounces

Answers

The total weight of the lettuce and carrots in ounces is 40 ounces if Samuel bought an 8-ounce bag of lettuce and two 1-pound bags of carrots option (D) is correct.

What is unit conversion?

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

We have:

Samuel bought an 8-ounce bag of lettuce and two 1-pound bags of carrots.

As we know:

1 pounds = 16 ounces

Amount of lettuce = 8 ounce


Amount of carrots = 2 pounds = 2×16 = 32 ounces

Total weight of the lettuce and carrots in ounces =  8 + 32 = 40 ounces

Thus. the total weight of the lettuce and carrots in ounces is 40 ounces if Samuel bought an 8-ounce bag of lettuce and two 1-pound bags of carrots option (D) is correct.

Solve the equation for exact solutions over the interval​ [0, 2π​).

Answers

Answer:

[tex]\displaystyle x=\left\{0, \frac{2\pi}{3}, \frac{4\pi}{3}\right\}[/tex]

Step-by-step explanation:

We want to solve the equation:

[tex]-2\cos^2(x)=-\cos(x)-1[/tex]

Over the interval [0, 2π).

First, notice that this is in quadratic form. So, to make things simpler, we can let u = cos(x). Substitute:

[tex]-2u^2=-u-1[/tex]

Rearrange:

[tex]2u^2-u-1=0[/tex]

Factor:

[tex](2u+1)(u-1)=0[/tex]

Zero Product Property:

[tex]2u+1=0\text{ or } u-1=0[/tex]

Solve for each case:

[tex]\displaystyle u=-\frac{1}{2}\text{ or } u=1[/tex]

Back-substitute:

[tex]\displaystyle \cos(x)=-\frac{1}{2}\text{ or } \cos(x)=1[/tex]

Using the unit circle:

These negatively charged molecular ions are characterized by the presence of hydrocarbon chains which are 12 to 18 carbon atoms long. How hard (solid, insoluble) or soft (liquid, soluble) a soap is depends on the nature of the anions and cations present in the system. Analyze how each of the following factors may affect the hardness or softness of soaps:1. The nature of the cations. For example, Na* vs Li* vs K. 2. The length of the hydrocarbon chain.
